Title: Method of forming insulation protecting film
Inventor: SAKAI MASAYUKI
IPC: H01L29/80
Filed: 1988-02-17
Abstract: PURPOSE:To fill a recess gate part with an insulating film completely and to flatten the surface, by incorporating a first step wherein an insulating film is deposited under a no-bias condition, a second step wherein the recess gate part is filled with the insulating film under the condition that is stricter than the condition for the first step, and a third step wherein a flat insulating film is formed with the etching intensity being weakened than that in the second step. CONSTITUTION:At first, an insulating film having a thickness of 1/3-1/2 the thickness of a recess part is formed under the no-bias state by an ECR-CVD method. Then, the film is well deposited on the bottom part of a narrow groove part. Then, a bias corresponding to an etching rate at which a depositing rate becomes about 1/8 in comparison with the no-bias state is applied, and an insulating film is deposited. Thus, the recess gate is filled. Thereafter, the etching intensity is weakened. An insulating film is deposited under a bias condition at which the depositing rate becomes about 1/2 in comparison with that in the no-bias state. Thus, flattening is achieved.

Abstract: PURPOSE:To achieve reflectivity of 70% or more by a simple structure and to secure recording characteristics and weatherability by using antimony trisulfide having nitrogen trapped therein in a recording film and laminating a gold reflecting film to the recording film. CONSTITUTION:An Sb2S3 film 2 having N2 trapped therein is laminated to a continuous group polycarbonate substrate 1 and an Au reflecting layer 3 and an ultraviolet (UV) curable resin film 4 are further laminated to the film 2.
